All image files created by the Digital Imaging Lab, which is part of the Digital Library at the University of Southern California, will be archived and repurposed as needs arise.
We strive to create files that adhere to best practices in the Cultural Heritage Imaging field, and we use the technical guidelines created by the Federal Agencies Digitization Guidelines Initiative (FADGI) as goal posts.
The Technical Guidelines for Digitizing Cultural Heritage Materials: Creation of Raster Image Files represents shared best practices followed by agencies participating in the Federal Agencies Digital Guidelines Initiative (FADGI) Still Image Working Group for digitization of cultural heritage materials. This group is involved in a cooperative effort to develop common digitization guidelines for still image materials (such as textual content, maps, and photographic prints and negatives) found in cultural heritage institutions. [Technical Guidelines for Digitizing Cultural Heritage Materials Creation of Raster Image Files, 2016]
While we strive to create the highest quality digital assets, we do minimal color correcting when post processing color transparencies. When we create an archival digital image, any distortions, discolorations or blemishes within the original item will appear in the digital file you receive.
Default file format specifications
All digital files will have the Adobe RGB (1998) color profile embedded.
Reflective photographs will be cropped just beyond the edge. Reflective materials will include a Golden Thread object-level target upon request.
Scanned Documents will be cropped to the edge. We do offer Optical Character Recognition [OCR] to be run on items that will be delivered as PDFs for a nominal fee.
Transparencies will be cropped beyond the edge of the exposure. Unperforated film and single exposures may include some or all edges of the substrate.
All image files are output to 16 bits per pixel (48 bit color). Grayscale or monochrome images will be output to 16 bits per pixel grayscale.
• Up to 4"x5": 2000-4000ppi. 16 bit tiff AdobeRGB or Gray Gamma 2.2. Captured using medium format digital camera systems and dedicated film scanners.
• 4”x 5” up to 8”x10”: 800-1200ppi, 16 bit tiff, AdobeRGB or Gray Gamma 2.2. Captured using medium format digital camera systems and flatbed scanners.
• Anything over 8”x10” is considered oversized and may result in a composite image to achieve resolution.
• Up to 11”x14”: 600 ppi, 16 bit tiff AdobeRGB or Gray Gamma 2.2. Captured using medium format digital camera systems.
• Larger than 11’ x 14” up to 20” x 24”: 400 ppi, 16 bit tiff, AdobeRGB or Gray Gamma 2.2. Captured using medium format digital camera systems and flatbed scanners.
• Anything over 20” x 24” is considered oversized and may result in a composite image to achieve resolution.
All digitized still assets will be output as 16-bit uncompressed TIFF files.
Pricing structure for digitization requests
We have two pricing options: one is for materials that will be digitized to support USC students and faculty/staff, and another for outside requests.
Payment will be processed through our Digital Library Store, which accepts all major credit cards. Files will be delivered through Aspera.
